Bradley Wiggins says it is "more than likely" he will sacrifice defending his Tour de France title to support team-mate Chris Froome in the 2013 race.

The route, revealed on Wednesday, is mountainous and will suit climbers such as Froome and Alberto Contador more than time-trial expert Wiggins.

"It's more than likely I'll ride in a supporting role for Chris," Team Sky rider Wiggins said. "I just want to be in a successful team."

"My objective will be the Giro."

Analysis

"The 99th Tour will not be forgotten by British cycling fans: you always remember your first time. But it will not go down as a classic elsewhere. Bradley Wiggins and Sky were just too good, on a course that played to their strengths. The 100th Tour, however, should be a lot closer. A first visit to Corsica, a team time trial, two ascents of Alpe d'Huez, a dusk finish on Paris - the canvas for something spectacular is there. It is up to the riders now."

But Kenyan-born Froome, 27, looked stronger than Wiggins in the mountains at times and, in a memorable moment, was ordered back to assist his team leader after breaking clear on Stage 11.

Wiggins appears more suited to next May's Giro d'Italia, which is less mountainous and includes more than 90km of time trials.

Next year's Tour de France - the 100th edition - will begin on the French island of Corsica on 29 June and end with an evening finish on the Champs-Elysees in Paris on 21 July, with the riders having cycled 3,360km.

There are several tough ascents, with Stage 18 featuring two climbs up Alpe d'Huez, while the length of the time trials has been reduced to 65km from 100km in 2012.

Team Sky principal Dave Brailsford said he would study the route in detail before coming to a decision about team leadership.

"We've very fortunate that we've got Bradley and Chris in the same team," he told BBC Sport.

"We'll have a look at the route and the rest of the races throughout the season and then we'll decide on our strategy to try and win as many races as possible."

The 2013 Tour contains three time trials - two individual and one for teams - as well as four summit finishes, not least a climb to Semnoz in the Alps on the penultimate day, which may determine the winner.

There is a chance for British sprinter Mark Cavendish, who has left Team Sky for Omega Pharma-QuickStep, to claim the first yellow jersey of his career on the relatively flat opening stage from Porto Vecchio to Bastia.

Brailsford still to pick leader for Tour

However, a Tour that also includes climbs up Ax 3 Domaines in the Pyrenees, as well as Mont Ventoux, is likely to favour the climbers.

Cavendish, who sits fourth on the all-time list with 23 stage wins in the Tour, including four in a row on the Champs-Elysees finale, said on Twitter: "Well, a spectacular course for 2013 Tour de France.
